Wiggle saved me having to buy a new MTBSo pleased to be able to purchase a 32" ring, it is becoming increasingly difficult to find this size, with 28" becoming the norm. It is wrong that I should have to scrap a perfectly good MTB Just because bike technology changes and spare parts for older models are no longer supplied.

This product was a straight replacementA very straightforward replacement on the XT kit. Installed with a new cassette and chain with a huge improvment in shifting.

Q & A

I have an xt m770 set up which is 10 speed

I need an xt m770 middle ring. my current set-up is 10 speed,
is this compatible as the description does not declare 9 or 10 speed. or can it be used on both 9 or 10 speed set -ups

Asked by: pupton

it's for 9 speed only, 10 speed is narrower.

Replaces sg-x m9 OK?

My middle Shimano chainring is a SG-X and is stamped &quot;M9&quot;' It is alloy.
Will this carbon inner, steel outerFC-M770 chain ring bolt straight in as a replacement?

Asked by: skood1

The M770 chainrings are a 104PCD Middle and outer and 64PCD inner sized so as long as you have the same PCD measurements on your current chainset these rings will fit fine. For a fit guide this is a useful guide; http://www.vueltausa.com/media/pdf/bcd_guide.pdf

What is the bolt hole PCD on this ring please?

Existign (old Deore LX?) PCD is 104 mm. Will this fit?

Asked by: CliffG

I can confirm that as the bolt hole is 104 mm BDC (aka PCD), this should fit without issue.
I hope this helps.

Will this chain ring fit a Truvativ Firex SX 2-Piece Crank?

Asked by: iturner77

I can confirm that as both your crank and the chainring share a 104 mm BDC, these should fit without issue.

32t or 44t?

The product is listed as 32t (so a middle ring) but the only product option is 44t (an outer ring) - which is it?
